RED – Don’t use red as the main color in your home, because it is a power color and full of passion. Use it sparingly, as an accent only, and you’ll get a lot of drama from it. A close companion to brown, red represents the core of earthy tonality and rustic textures. If your home is rooted in the landscape, shades of red like terra cotta or coral can be wonderful decorating colors. For a really vibrant pop look, mix red with primary yellows, greens and blues. For instance, paint it on your doors, window frames or other trim in the room. In a formal room, use a deep, dark red, such as burgundy, to compliment the dark woods in the room. Source
